2 / 20 page 1998 Sep 23 2 Philips Semiconductors Product specification 4 × 25 W BTL quad car radio power amplifier TDA8568Q FEATURES • Requires very few external components • High output power • Low output offset voltage • Fixed gain • Diagnostic facility (distortion, short-circuit and temperature pre-warning) • Good ripple rejection • Mode select switch (operating, mute and standby) • Load dump protection • Short-circuit safe to ground and to VP and across the load • Low power dissipation in any short-circuit condition • Thermally protected • Reverse polarity safe • Electrostatic discharge protection • No switch-on/switch-off plop • Flexible leads • Low thermal resistance • Pin compatible with the TDA8567Q, except for the gain. GENERAL DESCRIPTION The TDA8568Q is a integrated class-B output amplifier in a 23-lead Single-In-Line (SIL) plastic power package. It contains four amplifiers in BTL configuration, each with a gain of 40 dB. The output power is 4 × 25 W in a 4 Ω load. APPLICATIONS • The device is primarily developed for car radio applications.
